- The following is a list of 13 control plans from this chapter, followed by a list of 10 situations that have control implications. Match the 10 situations with the control plan that would best prevent the system failure from occurring. Because there are 13 control plans, you should have 3 letters left over. Control Plans A. Firewall B. Backup batteries and generators C. Insurance D. Employee badges, guest sign-in, locks on computer room doors E. Hot site F. Intrusion detection systems G. Off-site storage of backup computer programs and data H. Training (personnel development) I. Personnel termination procedures J. Security guards K. Program change controls L. Operations run manuals M. Fidelity Bond Situations 1. The computer users at the Identity Company do not know how to use the computer very well. 2. A computer hacker created a program to generate random user IDs and passwords. He used the random number program to access the computer system of Samson, Inc. 3. During the nightly computer run to update bank customers accounts for deposits and withdrawals for that day, an electrical storm caused a temporary power failure. The run had to be reprocessed from the beginning, resulting in certain other computer jobs not being completed on schedule. 4. A fire destroyed part of the computer room and the adjacent library of computer disks at Petunia, Inc. It took several months to reconstruct the data from manual source documents and other hard copy records. 5. A competitor flooded the Wolfeson Company Web server with false messages (i.e., a denial-of-service attack). The Web server, unable to handle all of this traffic, shut down for several hours until the messages could be cleared. 6. A group of demonstrators broke into a computer center and destroyed computer equipment worth several thousand dollars. 7. A computer programmer at Dover Company was fired for gross incompetence. During the two-week notice period, the programmer destroyed the documentation for all programs that he had developed since being hired. 8. The cash receipts clerk was on his way to the bank to deposit all the cash and checks received by the company that day when he decided that he would prefer to have a vacation in Brazil. The clerk kept the cash and cashed the checks. All the money was lost to the company. 9. A disgruntled programmer at the Going Company planted a logic bomb in the computer program that produced weekly payroll checks. The bomb was triggered to go off if the programmer were ever terminated. When the programmer was fired for continued absenteeism, the next weekly payroll run destroyed all the companys payroll master data. 10. The computer systems at Club, Inc. were destroyed in a recent fire. It took Club several days to get its IT functions operating again.arrow_forwardThe following is a list of six control plans from this chapter, followed by a list of five situations that have control implications. Match each of the five situations with a control plan that would best prevent the system failure from occurring. Because there are six control plans, you should have one letter left over. Control Plans A. Service level agreements B. Clear desk and locked door policy C. User manuals D. Biometric identification systems E. Program change controls F. Personnel termination control plans Control Situations 1. The customer service representatives at Everyday Supplies, a catalog sales company, have been complaining that the computer system response time is very slow. They find themselves apologizing to customers who are waiting on the phone for their orders to be completed. 2. George and Mike have been friends for many years. Henry works in the shipping department at Superior Company, an electronics wholesaler, and Mike is unemployed. To make a little money, Mike borrowed Georges employee badge (it has a magnetic strip on the back to open doors at Superior Company) and used the badge to access the Superior warehouse and steal some electronics gear. 3. At Bedrock Company, most transaction processing is automated. When an inventory item reaches its reorder point, the computer automatically prints a purchase order for the economic order quantity (EOQ). A programmer, who was in collusion with 3D-Arm, Inc., the vendor that supplied several parts, altered the computer program and the inventory master data for those parts. He reduced the EOQ and made certain program alterations, so that items supplied by 3D-Arm were ordered more often than Bedrock required them. 4. The data entry clerk in the accounts payable department at Martini Company did not have detailed instructions for completing the input form for approved vendor invoices. To speed up data entry, he let all of the date information default from the current days date. As a result, several invoices were paid late, and Martini Company lost cash discounts on several other vendor payments. 5. During a normal workday, James, who was not an employee, entered Tortora Companys offices and was able to find and remove some computer printouts containing user IDs and other sensitive information. He later used that information to gain access to Rowleys computer system.arrow_forwardExplain how internal control can be enhanced through the proper installation of Information Technology Identify the risks for accounting systems that rely heavily on IT functions. Distinguish between general controls and application controls and give examples at least five Which duties should be segregated in a computer department? Describe the typical duties of computer personnel. What aspects of documentation, file security and retention control procedures are unique to computer systems? What are the responsibilities of the database administrator (DBA) function? Compare the risks associated with network environment to those associated with centralized IT functions.arrow_forward
- Listed here are four scenarios. For each scenario, discuss the potential consequences and give a prevention technique. a) A company has recently installed a new computer network. The operating philosophy adopted by the new network administrator was to establish an open system that would foster work group date to the network users. To accomplish this objective, the data administrator assigned employee access privileges to data based on department and functional affiliation rather than specific tasks. b) Sara is a system programmer who was told she would be terminated in three weeks due to poor performance and was asked to conclude all of her projects during the three-week period. Two weeks later Sara created a logic bomb designed to get activated three months after her departure. Subsequently, the bomb destroyed hundreds of records in her previous employer’s accounts receivable invoice file. c) Matt discovered a new sensitivity analysis public-domain program on the Internet. He…arrow_forwardBelow are several statements about internal controls.1. The components of internal control are built on the foundation of the ethical tone set by top management.2. Once every three months, managers need to review operations to ensure that control procedures work effectively.3. Collusion refers to the act of a single individual circumventing internal control procedures.4. Detective control procedures are designed to detect errors or fraud that have already occurred, while preventive control procedures are designed to keep errors or fraud from occurring in the first place.5. Fraud committed by top-level employees is more difficult to detect because those employees more often have the ability to override internal control features.6. A good example of separation of duties would be having one person collect cash from customers and account for it, while having another person order inventory and maintain control over it.7. Employee tips historically have been the most common means of…arrow_forwardhas hired you to review its sales order procedures for internal control compliance and to make recommendations for changes. You are required to:a. Create a data flow diagram of the current system. b. Create a system flowchart of the existing system. c. Analyze the internal control weaknesses in the system. ; andd. Prepare a system flowchart of a redesigned computer-based systemarrow_forward
- Which preventive, detective, and/or corrective controls would best mitigate the following threat, and why? (d) An employee received an email purporting to be from her boss informing her of an important new attendance policy. When she clicked on a link embedded in the email to view the new policy, she infected her laptop.arrow_forwardThe flowchart illustrates the business activities of four departments, including (1) Production Planning and Control, (2) Work Centres, (3) Inventory Control, and (4) Cost Accounting. Examine these activities and determine any control threats. In particular, discuss the control problems, the possible dangers, and any corrective procedures you would recommend.arrow_forward
